Product Description
This is the first version of the Soma Fabrications Riff XC/Trail hardtail, no longer in production. The V2 changed to more modern "standards" like steeper and shorter seat tube, 148mm boost rear hub and comes only in aqua mint and pearl white. If you like the more neutral blue or you want something closer to your old school hardtail mountain bike this V1 is for you. Included is a Cane Creek Forty headset
This came to me with 3 fork options suitable for it. 1) Rockshox Reba RL 120mm cut to fit, 2) DIY Bikes rigid 482mm A-C cut to fit, and 3) brand new uncut Cotic 482mm A-C (coming tomorrow). All of these are shown with the fork at the end of the pics.
From the manufacturer
The Riff is our hardtail frame for 27.5″/650b wheels. It replaces the B-Side model. While the B-Side showed our tendency of keeping things old school, the Riff is modern without being trendy with the geometry and features. Tough Broski Sliding Dropouts allow you to go single-speed or geared or even run hub gears. Compatible with 12x142mm thru-axle hubs . A modified chainstay allows fitting even some double cranks with “plus size” 2.8″ wide tires without needing to invest in Boost parts. We even offer a belt-drive ready version.
Condition
Excellent to near mint lightly used shape. Zero dents/dings/bends/damage. Paint wear is pretty minor and scattered. The most obvious spots include a deep scratch on the top of the top tube a few inches from the head tube, small chips on the flat part of the DS chainstay, a few pinpoint chips on the seatstays, scuffing on bottom of non-driveside chainstay. This is well nicer than average wear for a mtb. Once built from a few feet away this will look close to new condition.
